Why not gray water?

Thinking this morning why not have a large tank, 1,000 gallon or more filled with shower water only? Aside from a separate pipe I would see now real drawbacks. The more you shower the more heat into the system. If done right you could plumb the tank to circulate the water in it also. Maybe add in the washing machine if you need more heat in the tank. Or would a small amount of bleach hurt the heat exchanger? Maybe sink a couple of car radiators and make a closed system for the heat pump in the water tank.

I don't know, it just sounds so dumb to use cold ground water when you could use the same water after you paid to heat it up...now I have to pay to get rid of it also? Why not get my heat I paid to put into the water back out, before it goes down the drain, so to speak?

Seems like a larger family would really benefit from this way also? No drilling, no digging in the yard.
